TENT-STRETCHING nnvIcn.

Application filed September 23, 1924. 7 Serial No. 739,317.

This invention relates to improvement'in tent stretching devices.

The prevalence of automobile touring has created a large demand for tents of the type sometimes referred. to as umbrella .tents. These tents are usually square and are supported by a single center pole. The upper edges of the walls are spread and stretched by some suitable means, such as sectional or telescopic bars which are insertedthru pockets in the tent walls near their juncture with the root-portion. As tents of this typeare employed mostly by automobile tourists, compactness is a matter of prime importance. We have therefore constructed our spreading devices as well as the center pole from tubular members which aretelescopirally related to each other so that the can be collapsed when not in" use. In or'c' erto hold the parts in extended :or adjusted position we have provided spring pressed detents which will behereinafter described.

()ur invention can be most clearly explained and will be most readily understood when reference is had to the accompanying drawing in which the same is illustrated and in which F 1 is a perspective view showing a.

tent in which our adjustable center pole and spreadcrs are employed.

Fig. 2 is a plan view, partly broken away, showing two of the four spreader'members employed. o 3 is a section taken on line 33,

'1 we have shown a tent wall side walls and a roof 2. The tent ings 8 which are adapted toreceive the pins and 3 where numeral 6 represents the larger V 9 that are attached to the free ends of the springs 10, the other ends of which are secured to the tubular member by means of a clamp '11. It is obvious that whenfthe pins 9 occupy the position shown in Fig. 3, the two members 6 and 7 will be locked againist relative longitudinal movement. Secured to they members 7near the outer ends thereof are springs 110 having pins 109 at one end and secured at the other end by clamps 111. Each'tent requires four telescopic bars such as shown in Fig. 3, all of which areof identical construction. Secured to the outer end of each member 6 is a coupling 12 havingtwo shanks 13 and 1 1 at right angles to'each other. The shank 13 is of the proper diameter to fitthe interior ofthefmember 6 and the shanlz l l is smaller and fits the inside of the member, 7. The couplings are secured to the end of member 6 by means of a pin 15. The shanks 1d have openings 16 for the reception of'the pins 109 (Fig. 3). Each coupling is also provided with an eyelet 17 for convenience in attaching a guy rope 18 thereto. After the four bars have been inserted into. the pockets 5 and properly connected, they will hold the tent square in the manner indicated in Fig. 1. The angular couplings which are anchored to the members 6 and 7 prevent the spreading devices from pulling apart when the tentois subjected to wind stresses. 2

The center pole 3 is preferably made from the tubular sections A, B, and G, which are telescopically connected one with the other. Section B has an outside diameter equalto the inside diameter or section A and section 0 fits the inside of section C. Sections A and B are provided at their upper ends with straps 19 which have an offset portion .20 within which a' spring 21 is located. This spring surrounds a pin 22 whose inner end 23 is enlarged and projects thru an' opening in the'wall of the section to whichit is at-f tached. Theend 23 is also adapted to pro- .ject thru openings 24 in t-he'wall of the inner tube so as'to lock the two adjacent tubes against sliding movement. By grasping the handle 231. the pin can be withdrawn from the hole intheinner tube so as to permit the pole to'he collapsed or extended; Holes 24 are provided near the upper as well as the lower ends of the tubes B and (3 so as to hold them in collapsed positiom Poles 25 constructed in a manner similar to that in which the center pole is constructed may be used to support the flap 26,, if desired.

\Ve desire to call pancicular attention to the constructionof the spreader bars illustrated in Figs, 2' and 3 and to-the fact that one end of each is provided with an angled coupling member 12 provided (at its corners) with aneyelet' "for the reception of a guy rope. The rigid coupling members with their right angularly related shanks serve to hold the spreader frame rigid and thereby hold the tent in proper shape. The angle connections also make it easy both to erect an'd'take' down the tent.

Ha vingnow described our invention, what we claim as new is:

I 1'. stretcher frame comprising a plural it? ofsu'hstantiall} identical bar members, each adapted to be inserted through a pocket in a tent one end of each bar' having an angular coupling a ttached thereto, said coupling having an opening adapted to receive a ay rope. the other end of each bar and the coupling having cooperating connecting means. I

A; stretcher frame comprising a plurality of substantially" identical bar" members, each formed from a plurality of tubular members telescopically associated with each other, one end of eachbarhaving a coupling member attached thereto, said coupling having two studs projecting at right angles to each other, one of said studs projecting into the bar with which it is associated the other stud being adapted to enter the other bar and an opening at the point oi intersection of" said studs;

3. A stretcher frame for tents compri ing four members adapted to respectively enter pockets formed at the junction of the side: walls" and root of a tent, each of said stretcher members being composed of a plurality of tubular telescoping arts and corner coupling members eachhaving two studs disposed at right angles to each other and of different size, the said studs being adapted to'respectively fit intothe larger and smaller ends of the" cooperating stretcher members of the frame which are correspondingly disposed for the purpose, each corner coupling memher being provided with an eye for convenience in attaching guy ropes;

In" testimony whereof we" aflix our signatures.
